What is the action level for noise exposure set by OSHA, above which a hearing conservation program must be implemented?

The action level for noise exposure set by OSHA is 85 decibels (dBA). This threshold is critical because it indicates the level at which employers are required to implement a hearing conservation program to protect workers from potential hearing loss. When noise levels reach or exceed 85 dBA averaged over an 8-hour shift, it is essential for employers to take appropriate measures, such as conducting noise monitoring, providing hearing protection, and offering training to workers about hearing conservation. This proactive approach aims to minimize the risk of hearing impairment that can result from prolonged exposure to high noise levels in the workplace. Ensuring compliance with this action level is vital for safeguarding employee health and maintaining workplace safety standards.
